Yes there is, it is:
⌃+⌥+⌘+R

You can use the above.

I am looking for a way to stop the current running script and restart it if a continuation is met.
How can I do that?
Write like this:
at_exit{
# whatever way you started the program originally such as `program_name`.
# Make sure that the new process is detached from the original.
}
and then do:
exit
somewhere where you want to break.

I often need to move file from one location to other, but it requires copying and pasting huge part of the command. For example:
mv ~/Projects/foo/bar/baz.img ~/Projects/foo/bar/fiz.dmg
Is it possible after entering ~/Projects/foo/bar/baz.iso part of above command to use some shortcut that duplicates it so I can change the very end to fiz.dmg?
You don’t need this:
mv ~/Projects/foo/bar/baz.img ~/Projects/foo/bar/fiz.dmg
easily turns into
mv ~/Projects/foo/bar/{baz,fiz}.img
. Note: zsh completion is still available when you write { (unless you have a habit of writing closing } right away) if you want it.
I actually discovered one possible solution. Just press:
Ctrl+W few times and then Ctrl+Y two times (and space between pastes).

How to exit from the long output of a terminal command or a git command like git log or git branch -a?
How to avoid that I have to press enter untill the output of the command is complete?
git log uses more or less for paging the output.
You can press q to stop more/less and drop the remaining output.
Ctrl-C is the entire answer, though it's too short to go in this field.

when i keep pressing Keyboard key 'A' at NOTEPAD, it input about 25 'A' to notepad per second, what controls the speed of input characters ?
Notepad is a giant EditBox. It's controlled by the system setting.
To read or write this value programmatically, use SystemParametersInfo(). Check out the section for Input Parameters.
